查询词典 HIV

If a pool tests positive for HIV, the individual sample can be detected and removed for further processing, and the donor can be deferred and notified (Kaiser Daily HIV/AIDS Report, 8/19/04). Because NAT looks for the virus and not antibodies, health professionals are able to identify HIV-positive patients in the days immediately following infection -- when they are most contagious -- which could help slow the spread of virus.

研究者以标准的艾滋病病毒抗体检测法检测时发现583例艾滋病病毒呈阳性反应的受试者，但是当他们用更加成熟的核酸扩增法检测那些呈阴性反应的受试者的时候，又发现了另外的23例病毒。

Basing on twice surveys of HIV-1 molecular epidemiology, HIV CRF01_AE strain has been introduced into inland neighboring provinces from southeastern coast areas and southwester border area, the prevalence of HIV CRF01_AE strains are increasing.

据全国两次分子流行病学调查结果表明HIV CRF01_AE重组型株正在从南部及沿海省市向周围省市扩散，CRF01_AE重组型在全国所占比例也有所增加，在福建省HIV CRF01_AE重组型为主要的流行株。

In many developing countries, the spread of HIV/AIDS has seriously affected their economic and social development. In 2001, the United Nations held a special GA session on this issue and adopted the Declaration of Commitment on HIV/AIDS. In 2006, it was declared at the high-level UNGA meeting on HIV/AIDS that the universal access to prevention, treatment, care and support would be realized by 2010, which has reinforced the efforts of the national governments to implement the declaration of commitment.

在许多发展中国家，艾滋病的肆虐已严重阻碍了他们的经济社会发展。2001年，联合国召开艾滋病问题特别联大，通过了艾滋病控制承诺宣言。2006年，联大艾滋病问题高级别会议宣布到2010年实现普遍获得艾滋病毒的预防、治疗、护理和支助服务的目标，进一步加强了各国政府落实承诺宣言的努力。

This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

它能够抑制自身免疫病的发生和发展，参与肿瘤免疫的调节，同时在感染和移植免疫中也发挥着极其重要的作用。T细胞的这一亚群具有免疫调节和免疫抑制的特性，新近发现它亦与爱滋病的发生、发展关系密切HIV进入人体后，CD4D25调节性T细胞抑制了机体的免疫效应但它也同时被感染，最终由于细胞毒的作用而死亡由于调节性T细胞数量的减少不能有效的发挥其抑制作用，HIV持续的过度活化使得T细胞逐渐耗竭说明在HIV发生、发展的不同阶段Treg细胞可能都发挥了免疫抑制作用，但是却对HIV感染与爱滋病发病的进程产生了不同的效应。

Objective To comparatively analyze HIV-antibody and biochemical detection results before and after serum samples were treated with heat-inactivation at 50℃ for 30 minutes and at 60℃ for 20 minutes. Methods 297 healthy individuals and 25 patients with positive HIV-antibody who were confirmed by HIV/AIDS confirmatory laboratory were involved into this study. Their blood samples were collected into three vacuum and desiccative tubes.

职业暴露感染，主要是指医疗器具不洁，造成接受医疗服务者感染HIV，其中也包括医务人员在提供医疗服务时，不慎被污染HIV的器具如针头、锐器等刺伤皮肤，或黏膜、破损的皮肤直接接触到含有HIV的体液，而被感染。

Viral replication and microbial translocation from the gut to the blood during HIV infection lead to hyperimmune activation, which contributes to the decline in CD4+ T cell numbers during HIV infection. Programmed death-1 (PD-1) and interleukin-10 (IL-10) are both upregulated during HIV infection.

加拿大蒙特利尔大学和美国佛罗里达免疫和基因治疗研究所的科学家合作进行的研究发现，膜蛋白PD-1和细胞衍生因子IL-10这两种分子联手作用，影响了艾滋病病人体内的CD4T细胞发挥正常作用，从而导致患者免疫系统受损并加快了患者病情的发展。

Before intervention, FSWs knew little about the knowledge of STDs and HIV/AIDS, and were imperceptive about the risk of being infected with HIV. There were quite a lot mistakes about their condom using. HIV related high-risk behaviors also existed. Comprehensive intervention need to be carried out urgently, widely and deeply in this population.

1。干预前性服务小姐性病、艾滋病知识水平低，对感染艾滋病的危险认识不足，在安全套的使用中存在许多错误，存在感染艾滋病的高危行为，需及时、广泛、深入地开展针对该人群的艾滋病综合干预措施。

Results The acception rate to HIV/AIDS was 15.1%,and it was influenced by their sex,education level,their awareness about the route and nontransmission,but it was not correlated to age,going out for work,living area and awareness to HIV/AIDS. Conclusion The acception rate to HIV/AIDS among the rural youth is low.

结果 农村青少年对HIV感染者/AIDS病人正确态度持有率为15.1%，并受到性别、文化程度、是否知晓艾滋病传播途径和是否知晓非传播途径的影响，而未发现其与年龄、是否外出务工、居住地、是否知晓艾滋病一般知识相关。

Result: 1. The situation of HIV infection in gastro-mucosal tissues:(1) Our study found HIV gag sequence in not only CD4~+ T cells but also mucosalepithelial cells, gland epithelial cells in lamina propria and spindle stromal cells;(2) HIV p24 was expressed in T cells, plasmocyte, and a few mucosa epithelial cells, gland epithelial cellls and dell epithelial cellls.

结果：1.HIV在胃黏膜中的感染状况：(1)HIV感染者胃黏膜内HIVgag区基因不仅见于CD4~+T细胞等免疫细胞中，少数胃黏膜上皮、腺上皮、小凹内上皮细胞和间质梭形细胞中亦有阳性杂交信号；(2)HIV感染者尸检胃黏膜内HIVp24蛋白于T细胞、浆细胞及少部分胃黏膜黏膜上皮、腺上皮及小凹上皮细胞中呈阳性表达。2。

ConclusionIt showed that there might exist HIV infection is some of HIV seronegative IVDUS at high risk of HIV infection.

结论抗-HIV阴性的静脉药瘾高危人群，存在潜在HIV感染。
